X-Wing

"The Incom T-65 X-wing is the fighter that killed the Death Star. An almost perfect balance of speed, maneuverability, and defensive shielding make it the fighter of choice for Rogue Squadron."
―General Carlist Rieekan

The X-wing was a prominent series of multiple starfighters produced by Incom with a characteristic "X"-shape of four wings, known as S-foils, extending out from the fuselage. These starfighters were found in the service of the Rebel Alliance, New Republic, and also the Galactic Alliance. They were originally meant for the Galactic Empire but when the entire Incom design team defected with the prototypes to the Rebel Alliance this deal was over. Despite this, however, at least one X-wing was stolen by a Stormtrooper.

TIE Fighters

"…Seinar System's [sic] basic TIE fighter—a commodity which, after hydrogen and stupidity, was the most plentiful in the galaxy…"
―Corran Horn

The TIE/LN starfighter,[18] or TIE/line starfighter, simply known as the TIE Fighter, was the standard Imperial starfighter seen in massive numbers throughout most of the Galactic Civil War and onward. Colloquially, Rebel and New Republic pilots referred to the crafts as "eyeballs."

Millenium Falcon

"You know, that ship's saved my life quite a few times. She's the fastest hunk of junk in the galaxy!"
―Lando Calrissian

The Millennium Falcon, originally known as YT-1300 492727ZED, was a YT-1300 light freighter with a storied history stretching back to the decades before the Clone Wars and the rise of the Galactic Empire. Manufactured by the Corellian Engineering Corporation in 60 BBY, the light freighter was first owned by Corell Industries Limited and underwent several name changes before being bought by the smugglers Kal and Dova Brigger in 48 BBY, and the ship eventually ended up as the property of the secretive Republic Group under the name Stellar Envoy by 29 BBY. The Envoy was destroyed in a collision with a bulk freighter above Nar Shaddaa, but it was rebuilt and served various owners under different names before Quip Fargil named it after the bat-falcon, and it eventually fell into the hands of Lando Calrissian after a game of sabacc—but Calrissian himself lost the ship in another game of sabacc to the smuggler Han Solo several years later.
